specific Embodiment approach 1

[0026] Specific implementation mode one: refer to figure 1 and figure 2 Specifically explain this embodiment, the ultrasonic water meter pipeline leakage and pipe burst detection method described in this embodiment, the method is realized by an ultrasonic water meter, and the ultrasonic water meter includes: an ultrasonic base meter 1 and an ultrasonic transducer 2;

[0027] There are two openings on the side wall of the ultrasonic base meter 1, and the two ultrasonic facing ends of the ultrasonic transducer 2 respectively pass through the two openings and are located inside the ultrasonic base meter 1, and the openings are sealed, and the ultrasonic transducer 2 The two ultrasonic opposing ends face each other,

[0028] The ultrasonic water meter pipeline leakage and pipe burst detection method comprises the following steps:

[0029] Step 1: Determine whether the ultrasonic water meter can collect signals, if so, perform step 2, otherwise, perform sensor failure / empty pipe...

specific Embodiment approach 2

[0036] Specific embodiment two: this embodiment is to further explain the ultrasonic water meter pipeline leakage and pipe burst detection method described in specific embodiment one. In this embodiment, the following steps are performed after step five:

[0037] Step 6: Determine whether there is user operation, if yes, accumulate the metering data obtained by the water meter, otherwise perform step 7;

[0038] Step 7: Record the time for the ultrasonic water meter to collect water flow, and make a difference between the time and the normal working time of the water meter. If the difference is greater than 2 hours, return to step 5, otherwise return to step 6.

[0039] In this embodiment, the ultrasonic water meter communicates wirelessly with the main control terminal of the water company. In order to save the internal power of the water meter, when the water meter is working normally, a continuous working time of 2 hours is set for the water meter to go online. Once there i...

specific Embodiment approach 3

[0040] Specific embodiment three: This embodiment is to further explain the ultrasonic water meter pipeline leakage and pipe burst detection method described in specific embodiment one or two. In this embodiment, the specific method for judging whether the ultrasonic water meter is installed in reverse in step two yes:

[0041] Make a difference between the reverse flow time and the downstream time collected by the ultrasonic transducer 2. If the difference is positive, the ultrasonic water meter is installed in the forward direction. If the difference is negative and the absolute value of the difference is greater than 3 seconds, the ultrasonic water meter is For reverse installation.

Abstract

The invention relates to the technical field of water meter pipeline detection, in particular to a pipeline leak and pipe burst detection method of an ultrasonic water meter. The pipeline leak and pipe burst detection method of the ultrasonic water meter aims at solving the problem that due to various defects of an existing mechanical water meter, pipeline leak or pipe burst can not be reasonably detected. According to the pipeline leak and pipe burst detection method of the ultrasonic water meter, data collected by the water meter is compared step by step, then whether a sensor fault / pipe emptiness, water meter reverse installation, water pipe burst and water pipe leak happen to the water meter or not is judged step by step, and thus the water pipe state is reliably and effectively detected. The pipeline leak and pipe burst detection method of the ultrasonic water meter can be widely applied to water supply metering of water supply companies.

Description

technical field [0001] The invention belongs to the technical field of water meter pipeline detection, in particular to an ultrasonic water meter pipeline leakage and pipe burst detection method. Background technique [0002] At present, there have been many disputes and disadvantages that are difficult to resolve in the project of using mechanical water meters. For example, due to the long-term wear and tear of the mechanical water meter, the accuracy of the heat meter is reduced, and eventually it cannot be used, causing the user to pay for maintenance many times, causing disputes that are difficult to resolve between the user and the water company (group); If it is in disrepair for a long time, the tap water pipeline will often leak by itself (the leak of the water pipe is small, forming a long-term small flow drip), or the tap water pipe will burst (the leak of the water pipe is large, forming a large flow of jet state), etc. There are many concerns and concerns about t...
